The secure display 11 includes an interference picture generator 111, a synchronization packet generator 112, a display unit 113, and a picture asymmetry generator 114. The interference picture generator 111, the synchronization packet generator 112, and the picture asymmetry generator 114 are implemented, for example, by a Timing Controller (Tcon) or a Micro Controller Unit (MCU). Privacy Privacy display method is applicable to the display system 1 and includes the following steps: First, as shown in step 31, the screen generator 111 generates the interference interfere with the picture signal N ₁ ~ N _n according to the normal picture signal S ₁ ~ S _n. Next, as shown in step 32, the screen asymmetry generator 114 controls the synchronous packet generator 112 to output the synchronization packet P to the secret glasses 12 based on the normal picture signals S ₁ to S _n and the interference picture signals N ₁ to N _n . Further, the picture asymmetry generator 114 generates the address code Add(n) and the mode code Mod according to the normal picture signals S ₁ to S _n and the interference picture signals N ₁ to N _n .

Further, the display unit 113 includes a panel 1131 and a backlight module 1132, and the backlight module 1132 provides a backlight to the panel 1131. The screen asymmetry generator 114 can control the panel 1131 or the backlight module 1132 such that the second luminance integral is greater than the first luminance integral. There are many ways in which the second luminance integral is greater than the first luminance integration implementation. For example, the screen asymmetry generator 114 controls the display time of the interference picture to be greater than the display time of the normal picture. Alternatively, the screen asymmetry generator 114 controls the display frequency of the interference picture to be larger than the display frequency of the normal picture. In addition, the screen asymmetry generator 114 can also control the backlight brightness of the interference picture to be greater than the backlight brightness of the normal picture. Alternatively, by increasing the pixel structure design of the fourth color sub-pixel, the brightness of the screen is relatively increased when the screen is disturbed, and the brightness of the screen is relatively lowered when the normal screen is displayed. In addition, the screen asymmetry generator 114 can also partition control the backlight module 1132 such that different backlight regions produce different backlight brightness.

Please refer to FIG. 5, FIG. 30 and FIG. 31, FIG. 30 is a comparison table when the security display 11 is in the 2D mode and the 3D mode, and FIG. 31 is a view showing that the security display 11 is in the 2D security mode and A comparison table in 3D privacy mode.

The picture signals S ₁ to S _n correspond. When the normal picture signals S ₁ to S _{n are} sequentially input to the picture asymmetry generator 114, the frame asymmetry generator 114 sequentially outputs the address code Add(n) as 1 to n. The screen asymmetry generator 114 sequentially displays the normal pictures F(S ₁ ) to F(S _n ) based on the normal picture signals S ₁ to S _n .

The picture asymmetry generator 114 generates the address code Add based on the address code Add(n). The address code Add can be used to indicate the address of the secret glasses to be transmitted by the synchronous packet generator 112. When the aforementioned secure display 11 operates in the 2D mode or the 2D privacy mode, the address code Add is the same as the address code Add(n). When the security display 11 operates in the 3D mode or the 3D security mode, since the normal pictures F(S ₁ ) to F(S _n ) are divided into a left-eye picture and a right-eye picture, the address code Add is equal to the address code Add ( One half of n). The command code Cmd is used to control the opening and closing of the corresponding security glasses 12.

When the command code Cmd is 0x01, the left lens 1282 is closed and the right lens 1281 is turned on. When the command code Cmd is 0x10, the left lens 1282 is turned on and the right lens 1281 is turned off.

The temporary storage unit 122 is configured to store a preset address, and the preset address is, for example, a preset glasses address and a preset broadcast address. When the address code Add matches the preset glasses address of the security glasses 12, it indicates that the security glasses 12 can detect the normal picture of the secure display 11. The preset glasses address of other secret glasses is different from the address code Add, and the normal picture of the secure display 11 cannot be perceived. When the address code Add matches the preset broadcast address of the security glasses 12, it indicates that the security glasses 12 can detect the normal picture of the secure display 11. Other security glasses having the same preset broadcast address can also detect the normal picture of the secure display 11. For the convenience of description, the following description will be made by taking the preset broadcast address and the preset glasses address of the security glasses 12 as 0x00 and 0x01 respectively.

Conversely, since the preset glasses address of the security glasses 13 is 0x02 and the address code Add is 0x01, it indicates that the synchronization packet P does not belong to the security glasses 13. Since the synchronous packet P does not belong to the security glasses 13, the decoder 123 outputs 0x00 so that the microcontroller 124 controls the right lens driver 1271 and the left lens driver 1272 to drive the right lens 1281 and the left lens 1282 to be respectively turned off. Since the user can perceive the normal image through the secret glasses only when the preset glasses address or the preset broadcast address of the secret glasses is the same as the address code Add, the confidentiality of the data display can be improved.

The mode code Mod is 0x01 indicating the 3D security mode, and the command code Cmd is 0x01 indicating that the right lens 1281 is on and the left lens 1282 is off.

When both the address code Add and the preset glasses address are 0x01, it indicates that the synchronization packet P belongs to the security glasses 12. The decoder 123 commands the code Cmd to output a command signal to the microcontroller 124. The microcontroller 124 controls the right lens driver 1271 to drive the right lens 1281 to be turned on according to the command signal, and controls the left lens driver 1272 to drive the left lens 1282 to be turned off according to the command signal.

Conversely, since the preset glasses address of the security glasses 13 is 0x02 and the address code Add is 0x01, it indicates that the synchronization packet P does not belong to the security glasses 13. Since the synchronous packet P does not belong to the security glasses 13, the decoder 123 outputs 0x00 so that the microcontroller 124 controls the right lens driver 1271 and the left lens driver 1272 to drive the right lens 1281 and the left lens 1282 to be respectively turned off. Since the user can perceive the normal image through the secret glasses only when the preset glasses address or the preset broadcast address of the secret glasses is the same as the address code Add, the confidentiality of the data display can be improved.

Please refer to FIG. 11, which is a schematic diagram showing that the security glasses are in the 3D broadcast mode. The main difference between FIG. 11 and FIG. 10 is that the synchronization code Sync, the address code Add, the mode code Mod, and the command code Cmd of the synchronization packet P of FIG. 11 are 0x55, 0x00, 0x00, and 0x01, respectively. The mode code Mod is 0x00 indicating the 3D broadcast mode, and the command code Cmd is 0x01 indicating that the right lens 1281 is on and the left lens 1282 is off.

The decoder 123 of the security glasses 12 outputs a command signal to the microcontroller 124 based on the command code Cmd. The microcontroller 124 of the security glasses 12 controls the right lens driver 1271 to drive the right lens 1281 to be turned on according to the command signal, and controls the left lens driver 1272 to drive the left lens 1282 to be turned off according to the command signal.

Similarly, when both the address code Add and the preset broadcast address are 0x00, it indicates that the synchronization packet P1 also belongs to the security glasses 13. The decoder 123 of the security glasses 13 outputs a command signal to the microcontroller 124 based on the command code Cmd.
